Ignition coil
Removal
Remove the luggage box, center cover.
Remove spark plug cap.
Remove the primary coil wire of ignition coil.
Remove the fix bolts for the ignition coil, and
remove the ignition coil.
Install the ignition coil in reverse order of
removal.
Caution
Spark plug confirmation
Remove the spark plug and install a good
plug into plug cap, and then ground it to
engine ground.
Make sure its spark condition. If it is in not
good or burnt spark plug, replace the spark
plug with new one.
Caution
Connect the high voltage shunt with a
multi-meter or input a resistor in the 10M
Ω
100V of voltage meter.
Connect ignition coil wires, and connect a
shunt between primary terminal (black/yellow
and green) and frame ground.
Press the starting motor button, or starting
lever to test the max. primary voltage of
ignition coil.
Connection: connect (+) terminal to green
side, and (-) to black/yellow side.
Min. voltage: Above 95 V.
Caution
Primary coil check
Disconnect the primary coil connector and
check the resistance between primary coil
terminals.

Primary coil is good if resistance within
standard.
Primary coil is broken if resistance is infinite.
Replace the coil.
Install primary coil with black/yellow lead
connected to black connector and green lead
connected to green connector.
Make sure each wire connection is correct,
and test as required. Even the wire
connection is in correct, sometimes, it
might not be tested occurred.
Do not touch metal parts on the test probe
with fingers to avoid electric shock.
